T0 ALL WHOM I'l MAY (3ONCERN:` l l Be it known that I., SAMUEL G. CABELL, of Quincy, in ,the county of Adams., and Stato ofmnois have invented o. new nndfnscful Improvement in Apparatus for 'Preventing' the Formation of Scale in Boilers,;. nd

removing such incrustation as 'may have becnzalready formed at the time'of its application; endl dofhereby declaro/that tbe following .is afull, clear, and exact description of thesame, reference being had to the accompartying drawings, forming part of this specification, in Wl1ich Figure 1 is'an velevation, partly in scction,.of the lopparatns, as constructed and arrnged,

Figure2 is on elevation, pcrtly'in section, of n multiplied or compound magnet detached, to be lapplied its shown atFing.1. A l, l l.

Figure 3 is o, horizontal section on the line :c on fig. 1.

Figure 4 is-a similar section on the line y y.

Figure 5 is a similar section on the line z z; and

Figure 6 is -an elevationofthe upper portion of thc batteyrused in,conection with the magnet shown inig.2.

Figure 7 is a. sectional view., showing the method of 'attaching theplato G tothe mognet L.,

The same let-ters nre employed in all-tbc figures in the indication o-i identicoliparts.

ITho object of this invention is to generate electric currents for the purpose setfor'th in the title hereof; and it consists in the application of nn electro-magnet, provided with o. number of points within o chmber'con- 'necting with the steam-chamber ofthe boiler-by means of a. pipe, having u. stop-cock by whichl to c'ut o' or .regulate its action, the helix otsaidmiignet being' connected with the poles of ari'electrifc'battery.

The following description 'will enable one skilled in the art to make and.. use my apparatus.

represents part of the 'shell oi a. cylindrical boiler, to which is attached 'the pipe B, provided witha stop-F cock,- B. This pipe maybe constructed with ianges; as shown in fig. 1,r by which the cylindrical chamber C may be ott-ached to it. On the uppeend'of this-chomber is bolted-thc stungbox D, withits followerE. The

magnet F, iig. 1, constructed as hereinafter described; passes through the stuffing-box D, -i'vhierc it is surrounded l and insulated by guttn' perche. or other suitablenon-conductor, and in the collar and lower part of the stuing-'box, it is sustained by stripsy of gutta'perchc, or other suitable insulators, arranged os' shown in fig. 5,'

the pa-lcing'in the stuing-box being steam-tight, as wellA as e"nonco nductor. About midway of the packing in A thestuingbox, the'magnet is provided with a coller secured-tp; it, which, bcing firmly clampedby the packing, prevents the steam from forcing up said magnet. This :mayalso be accomplished by otherjmeans, which it is l not necessary to describe here. On the lower end of lthe magnet F- is fastened, by menus of nl collur on its uppervside, ttingclo'sely around said magnet, as shown in iig. 7', and suspended within (und not'in contact with) y the chamber C, the plate .G, from thelower fac-e of which the pointed pins G prolicot.4 -Clhese points -arc'ci' soft iron or other suitable material, goldplnted,und tipped with platinum,:and being connected by means of the plate G, olf the smileA material, with the magnet F or L, become magnetic nbenevertbeelectric.circuit is closed.

The tube L is renderedmngnetic und constructed asoilotvs: An iron. pipefc'onstitutes the external' shell, and into this is inserted the .central core L', which is surrounded by u. copper wire, insulated' by being' coated with gott-a. percha or other suitable material. This wire is ooil'ediaiound the'coro L', from top to bottom and from bottom to top, so that the insulated wire is carried twice in coil-s,'oroftener if deemed necessary, ciongftbo entire length of the core, and'within the external shell.' Thofends o f the wire M crethen connected with the tvv'o poles oi' an-'electric or golvnnic battery, O, -and'the pipe and central core become-'nihgnetic bythe aetiofnof the'elec'tric or -gnlranic current. l v j l i u.

When this '.ippsratus is in use, the ground-oonnection 'isznnde by passing a wire through the hole q in the upper pointedtip I.4 The otherend of said wire, communicating with the ground, establishes thecurrent, by

which means tliceleotri'city received by the points G is conveyed od' and discharged fromtho boiler.

Having thusdescribed my invention, nhatI claim as' new, and desire-to secure by Letters Patent, is-- 1; The multipli-ed or compound electro-magnet- L, constructedsubstnntdlly as described, and arranged in combination with the lch'umbe'r C, points G, and battery essentially as described.

I ncrustaltion, substantially :is specified.
